Script that creates self extractable executable from tar.gz file.
The result can be executed directly and extracts content of give tar.gz to current directory.
Script arguments: (mandatory) tar.gz file path and (optional) command that will be executed right after extracting the tar.gz content.

The name of resulting executable is as name of tar.gz with suffix ".self"

Usage:
Create self-extracted executable: ./selftar.sh my.tar.gz
Create self-extracted executable: ./selftar.sh my.tar.gz "folder/install.sh"

Both examples create file my.tar.gz.self
